A heat pipe mounting method and a heat pipe assembly thereof are disclosed. The method includes the step of providing a heat-transfer block and a plurality of heat pipes. A plurality of heat pipe grooves is formed on the heat-transfer block. The heat pipes are then press-fitted to respective heat pipe grooves. During the press-fitting step, the heat pipes are flattened to force the flattened part of one heat pipe into abutment against the flattened part of another heat pipe in a flushed manner. Thereby, the heat pipes are abutted to each other with no separation therebetween. Hence, the heat transfer performance is increased.

The present application is a division of prior U.S. application Ser. No. 13/178,489 filed Jul. 7, 2011, entitled “HEAT PIPE MOUNTING METHOD AND HEAT PIPE ASSEMBLY THEREOF”. The prior U.S. Application claims priority of China Patent Application No. 201110052053.4, filed on Mar. 4, 2011, the entirety of which is incorporated herein by reference.
(a) Field of the Invention
The instant disclosure relates to a heat transfer technology; more particularly, to a heat pipe mounting method and a heat pipe assembly thereof.
(b) Description of the Prior Art
A heat-transfer block is often used with heat pipes to enhance heat transfer performance. To accommodate the heat pipes, the heat-transfer block is often provided with heat pipe grooves. These heat pipe grooves are spaced from one another by certain distance, i.e., the heat pipes cannot be closely arranged together. Thus, the number of heat pipes allowed for the heat-transfer block is restricted. In addition, the heat transfer among the heat pipes is unsatisfactory. Namely, the outer heat pipes are farther away from the heat source, thus the heat transfer performance is less effective. Because the heat pipes are spaced apart from one another, the inner heat pipes cannot transfer heat directly to the outer heat pipes.
Furthermore, when securing heat pipes to respective heat pipe grooves of the heat-transfer block, a soldering material is often employed. Alternatively, solder-less press-fit method may be employed to affix heat pipes to respective heat pipe grooves of the heat-transfer block. These heat pipe grooves may be configured to provide arched or oval cross sections. When the heat pipes are forced into respective heat pipe grooves, the heat pipes are pressed fitted to prevent accidental separation. However, because the heat pipe grooves have arched or oval cross sections, the heat pipes tend to be loosened or forced out of position accidentally in absence of the soldering or adhesive materials. Further, for more than one heat pipe, the oval-shaped heat pipe grooves force these heat pipes to be spaced further apart from one another. Due to such limitation, the heat pipes cannot be closely arranged. On the other hand, if the soldering material or paste is opted to secure the heat pipes, the following issues may occur. If not enough soldering material or paste is available, the heat pipes may be loosely attached. However, if too much soldering material or paste is applied, the excessive amount would overflow the grooves as an eyesore to the users. Other disadvantages include the increase in material and manufacturing costs.
To address the above issues, the inventor strives via industrial experience and academic research to develop the instant disclosure, which can effectively improve the limitations as described above.
One aspect of the instant disclosure is to provide a heat pipe mounting method and a heat pipe assembly thereof. When multiple heat pipes are disposed on a heat-transfer block, the heat pipes are arranged next to each other without separation. Thus, the heat transfer performance can be enhanced.
Another aspect of the instant disclosure is to provide a heat pipe mounting method and a heat pipe assembly thereof, which employs a solder-less press-fit method to firmly secure the heat pipes to respective heat pipe grooves of the heat-transfer block, avoiding displacement of the heat pipes. This method is applicable to the semi-circular shaped heat pipe grooves for grouping the heat pipes effectively.
To achieve the above objectives, the heat pipe mounting method of the instant disclosure includes the following steps: a) providing a heat-transfer block and a plurality of heat pipes, wherein the heat-transfer block has a plurality of heat pipe grooves formed thereon, and a supporting rib is formed between each heat pipe groove, wherein a tip portion is defined on each supporting rib; b) press-fitting the heat pipes into respective heat pipe grooves; and c) flattening the heat pipes to force the flattened part of one heat pipe into abutment against the flattened part of the other heat pipe when press-fitting the heat pipes into the heat pipe grooves, wherein the heat pipes abut to one another without separation.
The heat-transfer block has a surface, wherein a plurality of heat pipe grooves are orderly formed thereon in close proximity, and a supporting rib is formed between each heat pipe groove, wherein a tip portion is defined on each supporting rib. The heat pipes are press-fitted into respective heat pipe grooves. An abutting portion is formed on each heat pipe along the tip portion of the supporting rib. The abutting portion of each heat pipe is flushed with the abutting portion of the adjacent heat pipe.
The various objects and advantages of the instant disclosure will be more readily understood from the following detailed descriptions when read in conjunction with the appended drawings. However, the appended drawings are for references and explanation purposes only, therefore are not used to restrict the scope of the instant disclosure.
